Maurice, I call my location "the epicenter of evergreen". I live a block from the beach, on an island and officially somewhere between 9a/9b. I think 9a is appropriate but we haven't had a freeze in 10 years. I've learned the hard way to research parents before I buy a cultivar. Often that doesn't help when the target cultivar and it's parents are all described as SEV. Interestingly, some cultivars are labeled "EV" even when 1 parent is dormant. That is the kiss of death in my garden. I have a short list of daylilies that have dwindled ... there are more on my "Lost and Tossed" list. Failure to thrive isn't unusual here.
These daylilies have dwindled to nothing:
Guilded Knight
Ring the Bells of Heaven
Royal Celebration
Texas Big Red
Winter Tapestry
